On Tuesday, Sept. 24, the 20-year-old boy-bander confirmed the not-so-surprising news on Twitter. "So, I guess it's obvious now," he wrote. And while not specifically mentioning what made their relationship "obvious," we're inclined to think it was these recent pics of the duo looking very together at Disneyland.
"thanks to everyone who is being so lovely," Nathan added. I'm so happy #butweareterrified #pleasedontkillme #orariana."
Ariana, 20, retweeted her newly official beau., "we hesitated saying anything as people can be a bit insensitive but thank u," she added. "we value all of your happiness, thank you for valuing ours."
Earlier this month, the Sam & Cat star played coy on her relationship status, telling E! News, "I'm happy. I'm trying to figure everything out…I have a very open relationship with my fans, so I feel like when there's something to be said it will be said."
And that time was now!
